Often patients with ankle fractures that are stable, and thus do not require surgery, are given follow-up x-rays because their orthopedists are concerned about possibly having misjudged the stability of the fracture. When a number of follow-up x-rays were reviewed, however, all the fractures that had initially been judged stable were found to have healed correctly. Therefore, it is a waste of money to order follow-up x-rays of ankle fractures initially judged stable. Which of the following, if true, most strengthens the argument?

Which of the following, if true, most strengthens the argument?

A、
A. Doctors who are general practitioners rather than orthopedists are less likely than orthopedists to judge the stability of an ankle fracture correctly.
B、
B. Many ankle injuries for which an initial x-ray is ordered are revealed by the x-ray not to involve any fracture of the ankle.
C、
C. X-rays of patients of many different orthopedists working in several hospitals were reviewed.
D、
D. The healing of ankle fractures that have been surgically repaired is always checked by means of a follow-up x-ray.
E、
E. Orthopedists routinely order follow-up x-rays for fractures of bones other than ankle bones.

专业教师答疑

问题：请@tina老师回答一下。我读原文感觉就是患者的ankle fracture比较stable的不需要手术，只用后面来做几次followup x-rays就可以了。然后又说x-rays通常显示没问题，所以做这个x-rays就是浪费钱。问题是要支持原文。我的理解就是要支持做x-rays浪费钱。然后看到选项感觉都没有支持这个的感觉。答案c我也是想半天感觉也没有支持做x-rays浪费钱啊？！查看答疑

问题：我对原文的理解是，一些被诊断为stable fracture的病人都被要求一个follow-up x-ray，因为医生怕误诊。但是review x-ray后都会发现这些stable fracture治愈了。因此作者认为拍follow-up x-ray是浪费钱的。但是我不太理解正确选项为什么对，它的意思是review的样本量足够大，所以增加了结论可信度吗？查看答疑

问题：这个题目我大致看成了这样：通常病人有stab关节fracture的不需要手术的，被给了一个后续x片因为有可能被误诊关于稳固性。当一个后续的x片被看时发现所有的stable处都正确愈合了。因此，很浪费钱去买后续x片关于那些一开始认为stable的。 A 有两帮医生p和o，p比o更不可能正确判断关节稳固性，这个强调的是p和o的比较，排除了； B 很多关节受伤被揭示发现没有任何fracture 这句话是在讲什么？按照一句话讲一件事的定义，他说的是injuries有没有fracture吗？ C x片属于病人的这个病人属于很多不同的o来自不同的医院被审核了。说实话这个我压根没有看懂看文章的时候也不记得有o了直接跳过了然后我觉得c只是说x片被看过来所以也排除了 D 讲的是愈合经常被一种方式检查排除了 E o经常要后续x片关于fracture而不是ankle的，我觉得在讲x片怎么样了，好像沾边啊？就稀里糊涂的选了E 看了现有的解释没有一个是回答了我的问题的请老师用第一遍做题的感觉帮我看一下我到底哪里出问题了谢谢老师！读成这样能做题吗？查看答疑
